Title: Motor
Inventor: KIYOMA TOSHIAKI
IPC: H02K21/24
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To obtain a motor the starting time of which does not fluctuate much when the motor is manually driven with a sensorless drive circuit which does not require any position detecting element, such as the Hall element, etc., by constituting a bracket which fixes a stator coil and bearing so as to produce magnetic unbalance. SOLUTION: A magnet 1 and shaft 2 are respectively fixed to one surface and central part of a rotor frame 3. A stator coil 5 is wired on a flexible printed board 6 and fixed to a bracket 7 so that the coil 5 can be counterposed to the magnet 1. A bearing 4 which rotatably supports the shaft 2 is fixed to the bracket 7 and the bracket 7 has a notched section 9 so that unbalance can be produced in a magnetic circuit in the notched section 9. Therefore, the fluctuation of the starting time of a motor can be reduced when the motor is driven with a sensorless drive circuit which does not require any position detecting element, such as the Hall element, etc.

Title: Displacement converter
Inventor: KUWABARA HAJIME
IPC: G01D5/347
Filed: 1982-10-07
Abstract: PURPOSE:To improve the substantial resolution and responsiveness of a displacement converter, by extracting a time-series output signal out of a set of light emitting and photodetecting elements and at the same time to give a contrivance to the signal processing system. CONSTITUTION:A code bar 2 contains four light transmitting part groups 21-24 formed while overlapping an each other to the light transmitting part of a code piece 1 with the phases shifted by 90 deg.. The light emitting elements 31-34 are driven selectively by the signal of a decoder 12 in response to the count value of a counter 11. An amplifier 13 is used to obtain the sum of output signals of photodetecting elements 41-44. A BPF14 extracts a basic wave component 23 out of the output signal of the amplifier 13. A sine wave signal 23 serving as a basic wave has a phase difference phi with respect to driving signals 211-214 of the elements 31-34. This difference phi corresponds to the relative revolving angle between the piece 1 and the bar 2 and shows a revolving angle within an interval of the light transmitting part of the piece 1. Thus it is possible to measure the phase difference phi with 1/1,000 resolution if the dividing ratio of the counter 11 is set at 1,000, for example.

Abstract: PURPOSE:To obtain an excellent battery which causes no hydrogen generation, is excellently charged at minute current and causes no liquid leakages due to puncture by adding an amount corresponding to the variation in capacity of a nickel plate of Cd(OH)2 to the plate. CONSTITUTION:A base plate of around 80% porosity prepared by sintering nickel powder, after being immersed in mixture solution consisting of, for example, 92mol% nickel nitrate, 5mol% cobalt nitrate and 3mol% cadmium nitrate, is subjected to electrolytic reduction in 30% sodium-hydroxide solution so as to codeposit the hydroxides of nickel, cobalt and cadmium. After that, the base plate is washed with water before being dried. Such a series of processes are repeated five to six times so as to pack the base plate with a given amount of the active materials. After that, the base plate is immersed in 600g/l aqueous cadmium nitrate solution, thereafter being subjected to a similar operation once so as to pack it with an additional amount of around 4mol% of free cadmium hydroxide which is an antipolar substance. Such a positive plate thus formed is finally subjected to usual formation treatment in aqueous alkaline solution thereby being completed.
